BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image creating apparatus and an image displaying apparatus capable of creating and displaying image data in both a horizontal display device and a vertical display device.

[0002]

2. Description of the Related Art CRT (cathode ray tube) for displaying images, LC
As shown in FIG. 7A, the display device such as D (liquid crystal display element) is installed horizontally, that is, the long side of the display surface is positioned above and below the image (characters, figures, etc.). Mostly used. Therefore, in the conventional image creating apparatus and image display apparatus, it is premised that the display apparatus is used horizontally. Then, in the horizontal display device, as shown in FIG. 7B, scanning is performed in parallel with the long side of the display surface from left to right and from top to bottom. Therefore, the display memory used in the image creating apparatus and the image display apparatus is shown in FIG.
As shown in (A), the number of pixels corresponding to the long side of the display surface is larger than the number of pixels corresponding to the short side, and each pixel of the display memory and the display surface of the display device. The positional relationship of is as shown in FIG. 8B so as to match the scanning direction.

Here, when a so-called bitmap image is created on the creating device side and the display side develops the bitmap data in the display memory (1), the creating side does not drop the bitmap, for example, a character. A case where the string is sent to the display side as character code string data and the character pattern is extracted from the character code and displayed on the display side will be considered separately from (2).

First, in the case of (1), on the creating side, a bitmap image is created so that the long side of the horizontal display device is located above and below a character or graphic. When using a character string as part of a bitmap image, the direction in which one character is written and the next character is written (hereinafter referred to as the character string display path) is horizontal. The character string is parallel to the long side of the display device. From left to right, the vertical writing string is from top to bottom parallel to the short side of the display device. Next, in the case of (2), the creating side does not read the character pattern from the character code, but sends the character string data to the display side as the character code string data. The display side knows the character to be displayed from the sent character string code, reads the pattern of the character, and writes it in the display memory so that the long side of the horizontal display device is located above and below the character. In the character string display path, a horizontally written character string is parallel to the long side of the display device from left to right, and a vertically written character string is parallel to the short side of the display device from top to bottom.

In any of the above cases (1) and (2), as shown in FIG. 9, the characters are displayed such that the long sides of the horizontal display device are located above and below the characters, and the character string is displayed. In the path, the horizontally written character string is from left to right in parallel with the long side of the display device, and the vertically written character string is from top to bottom in parallel with the short side of the display device.

[0006]

By the way, for display effect, as shown in FIG. 10, the display device is set vertically, that is, the short side of the display surface of the display device is set above and below a character or an image. Sometimes used. In this case, a device that rotates the deflection system of the display device by 90 degrees and scans from left to right and from top to bottom parallel to the short side of the display device is also conceivable.
Since there are few applications for vertical installation, the cost is high, and in reality, vertical display devices are rarely made. Therefore, in most cases, the entire horizontal display device is rotated by 90 degrees and used as a vertical display device. FIG. 11 (A),
As shown in (B), in the case of horizontal placement, the horizontal writing character string is from left to right in parallel with the long side of the display device, and the vertical writing character string is from top to bottom in parallel with the short side of the display device. In the case of vertical placement, we want horizontal writing strings to be parallel to the short side of the display device from left to right, and vertical writing strings to be parallel to the long side of the display device from top to bottom. The device and the image display device have a problem that they are displayed as shown in FIG. 10 and cannot be used as a vertical display device.

The present invention has been made in view of the above problems, and an image creating apparatus for creating an image that can be displayed on both a horizontal display and a vertical display, and a horizontal display. An object of the present invention is to provide an image display device capable of displaying a created image on both a stationary display device and a vertical display device.
